CUT, A CORZPORATION OF CONNECTICUT 0F BRIDGEPORT, CONNECTI- HEATER CONNECTER Application filed May 28, 1929. Serial No. 366,552.

The present invention relates to heater connecters and is more particularly directed toward a heater connecter suitable for use with "flat irons, percolators, electric toasters. and

thelike, and which is provided with side receptacles or convenience outlets adapted to receive attachment plug. caps or the like.

The present invention contemplates a heater connecter for the purposes above reterred to by means of which one can connect a single supply circuit not only to a toaster, percolator or the like, but a so plug in other circuits, employing the heater connccter as a tap for making these connections.

In the preferred form 01 constrmzt on. the heater connecter is made out of two identical casino; halves of molded insulating material and the conductor assembly for each side of the circuit is seated in suitable recesses or chambers formed in the insulating halves. The device is suitable for use with a single appliance such as the toaster, percolator, or the like. but when it is not so employed. the side outlets are available for connecting in other appliances or the device may be used as a connection block for plugging in two circuits. The main heater connecter contacts are out of use but are protected by the casing.

The multiple tap heater connecter of the tvpe described herein may be produced at little additional cost'over the cost of the standard heater connecters for only one appliance.'and it is also possible to design the casing of this type of heater connector so that it is more easily gripped to pull it from the terminals of the appliance. than is the case in the ordinary type of heater connector.

The accompanying drawings show. for purposes of illustrating the present invention, one of the many possible embodiments in which the invention may take form. it being understood that the drawings are illustrative of the invention rather than limiting; the

same.

In these drawin as:

Figure 1 is a side elevational view of the complete heater connector:

Figure 2 is an elevational view showine the conducting parts held in place in one of the casing halves;

the casing Figure 3 is an elevational view of one of ted;

Figure 4 is a section taken on the line 1- 1 of Figure 2; V

Figure 5 is an elevational view of one of the terminal assemblies; and

Figure 6 is an elevational view latine, strip.

According to the form of construction'of the heater connecter illustrated in the drawinns, it is made up of two casing halves 10 and 11 of general rectangular shape. These casino: halves may be provided with annular recesses 12 to accommodate the usual coiled spring 13 employed in heater connecters for the purpose of protecting the current supply cord.

The casine halves are each provided with longitudinally extending grooves 14 and 15 and transverse grooves 16 and 17 arranged opposite one another to form chambers adapted to receive the conducting parts. designated generally by the reference characters 18 and 19. These conductor assembl es are similar to one another except that the conductor assembly 18 is arranged for the upper set of blade receiving contacts and the of an insuconductor assembly 19 isarranrzed for the lower set of blade receivin contacts.

The left conductor assembly 18 consists of a pair of conducting aws 20 adapted to cooperate with the pin type terminals emp oyed in flat irons, percolators and the like. These jaws are secured to a strip 21 by a rivet indicated at 22. The strip is bent rearwardlv to provide a shoulder indicated at 23 so that the portion of the strip 21 above the shoulder 23 is in a plane back of the port on riveted to the jaw contacts. The portion 21 extends upwardly as indicated in Figure 5 and is then bent forwardly to provide a shoulder indicated at 24. The upper end of the strip 21 is punched and threaded to receive a screw 25. The stri 21 is prov ded with a forwardly extending portion 26 which is bent as indicated at 27 to be in a plane parallel to the plane of the main body part of the strip 21. The portion 27 is provided with a forwardly bent member halves with the metal parts omit-- 28 to which is riveted a cross strip 29 bent back on itself as indicated in the drawings to form a pair of blade receiving contacts.

The right conductor assembly 19 is similar to the conductor assembly 18 except that the strip 21 corresponding with the strip 21 is provided with bent portions 26, 27 and 28 corresponding to the parts designated as 26, 27 and 28 in Figure 5. These bent portions are placed nearer the conducting jaws than in the other conductor assembly. These bent portions are adapted to support lade receiving contacts or spring terminals 30 similar to the contacts or terminals 29. he strip 2lalso carries a binding screw 25 corresponding with the screw 25.

The configuration of the recesses and passageways 14, 15, 16 and 17 in the insulating casing halves are such as to receive the conductor assembly above described. The jaws 20 and 20 are received in the lower parts of the longitudinal passageways 14 and 15, these passageways having suitable configuration as indicated to receive the jaw members. The portions of the longitudinal passageways 14 and 15 above the pockets for the jaws are narrow and deep as indicated at 32 and 33. these parts being ada ted to accommodate the strips 21 and 21. The upper ends of these passageways 32 and 33 are diverged as indicated at 34 and 35 and adapted to receive corresponding portions of conductor assemblies. The casing halves are provided with recesses 37 and 38 o accommodate the screws 25 and 25. The transverse recesses 16 and 17 are shallower than the portions 32 and 33 of the long tudinal recesses and are adapted to receive the cross conductor strips 30 and 29, respectively. They also receive the portions 27 and 27' of the longitudinal conductor strips. so that the conductor assemblies are prevented from moving longitudinally of the casing.

In order to prevent arcing between the blade receiving contacts and the conductor strips of opposite polarity, insulat ng strips 39 and 40 made of mica or other insulating material are interposed between the body port-ion E21 and 21 of the strips and the cross conductor strips above them as appears in Figure 4. These strips are of such length that thev are merely dropped into place and are held there by the shape of the parts.

and 25, and easing halves secured together by bolts 41 in the usual manner. In use, the heater connector may be connected to a flat iron. percolator, or the like, by employing the jaws 20 and 20. One can readily connect side or branch circuits by merely using the ordinary attachment plug cap which may be inserted into the openings provided by the transverse recesses 16 and 17. The heatconnection only to one All theparts are readily made by molding and stamping operations.

In order to surround the lateral plug receiving holes with suflicient insulating material, the casing halves are provided with enlargements or bosses 42 and 43 and when t e device is assembled these pairs of bosses are opposite one another thus affording a convenient grip to facilitate pulling the connector off the device to which it is attached.

I claim:

A heater connector recesses, the portions cesses adjacent the transverse recesses being deeper than the transverse recesses, conductor strips fitting the longitudinal recesses l carrying jaw contacts at their lower ends, the strips having lugs to which are secured transverse spring terminals disposed in the transverse recesses, and insulating strips overlying the longitudinal conductor strips and underneath the transverse strips.
